Grade thresholds
| Score range | Grade | Interpretation |
|---|---|---|
| 90–100 | A — High Transparency | All ten dimensions answered; COA pre-purchase; full contaminant panel; named lab; DSHEA-compliant claims; named leadership; 500+ reviews. |
| 75–89 | B — Strong Transparency | Most dimensions answered; minor gaps in COA specificity or review footprint. iMicrodosing.com scored 80/100. |
| 60–74 | C — Partial Transparency | Some consumer questions answered; important gaps in testing disclosure or ingredient specificity remain. |
| 40–59 | D — Low Transparency | Heavy reliance on vague claims; incomplete testing disclosure; unclear ingredients or proprietary blends. |
| Below 40 | F — Very Low Transparency | Insufficient information for an informed consumer decision. Regulatory action has been documented at this tier. |
TL;DR
The framework scores only what is publicly visible. A brand can have excellent internal quality controls and still score low if that information is not accessible to a consumer before purchase. The reverse is also true: visible COAs and restrained claims raise the score regardless of what internal processes produced them.
Key facts
What you need to know
- 1COA Visibility (10 pts): Batch-specific Certificate of Analysis accessible before purchase, from a named accredited third-party lab, linked from the product page. On-site labs and facility certifications (BRCGS, ISO) are not equivalent — they scored lower.
- 2Lab Panel Clarity (10 pts): Full contaminant panel visible: potency, heavy metals (Pb/As/Cd/Hg by ICP-MS), microbials, pesticides, solvents. Potency-only COAs score lower. The panel should be readable without downloading a file or creating an account.
- 3Ingredient Transparency (10 pts): Every ingredient named with species (not just 'mushroom blend'), format (fruiting body vs. mycelium), and extraction method where applicable. Proprietary blends with total weight but no per-ingredient amounts scored lower on this dimension.
- 4Dosage Clarity (10 pts): Per-serving compound amounts, serving size, and frequency guidance in plain language. 'Suggested use: 2 capsules daily' without stating mg per capsule scored below brands that stated both the total and the per-capsule amount.
- 5Medical Claim Restraint (10 pts): 10 = zero disease-treatment claims on any commerce page. Disease claims ('treats anxiety,' 'replaces medication,' 'clinically proven to cure') are not permitted for dietary supplements under DSHEA without FDA pre-market approval. Structural/functional language is permitted.
Evidence breakdown
What the data shows
Legal Disclaimers (10 pts)
Full DSHEA disclaimer on every product page, pregnancy/lactation caution visible, and no unsupported jurisdictional claims. 'These statements have not been evaluated by the FDA' must appear near any structure/function claim. '100% legal everywhere' is never accurate.
Support Availability (10 pts)
Named company leadership, working phone number, email, and live chat or equivalent, plus a named physical location or registered address. Anonymous contact forms only scored lower. Leadership names verifiable via BBB or state business registration scored highest.
Shipping Transparency (10 pts)
Processing cutoff time, named carriers, free-shipping threshold, expedited pricing, and lost-order policy — all on a dedicated, findable page. iMicrodosing.com's dedicated shipping page scored 9/10, the highest in the audit on this dimension.
Review Visibility (10 pts)
Independent third-party review footprint: Trustpilot (500+ reviews threshold), BBB accreditation, Google Business Profile present. Brands with fewer than 100 Trustpilot reviews and no BBB scored lower. Review count, not rating, was the primary signal.
Refund / Replacement Clarity (10 pts)
Dedicated policy page, clear return window (30+ days), stated conditions, return process clear. Brands with documented customer complaints about subscription cancellation difficulty (MUD\WTR, Mojo) scored lower on this dimension regardless of published policy language.
Verdict
The 100-point framework is a consumer tool, not a regulatory one. It asks one question: can a consumer understand what this product is, what it contains, who made it, how it was tested, what the risks might be, and how to get help — in under 90 seconds, from the product page alone? Most audited brands cannot answer yes to all ten of those questions.
Common questions
Answered directly
Why is on-site testing not equivalent to third-party COA?
An on-site lab tests the same company's products in a facility the company owns. A third-party accredited lab (ANAB/ILAC-MRA or equivalent) is independent. Both can produce accurate results; only the third-party lab eliminates the conflict-of-interest question that a consumer cannot otherwise resolve.
What is DSHEA and why does it matter for claim restraint?
The Dietary Supplement Health and Education Act (1994) permits manufacturers to make structure/function claims ('supports immune health') without pre-market FDA approval. Disease claims ('treats cancer,' 'cures anxiety') require FDA approval as a drug claim — a standard almost no supplement brand in this audit meets for its mushroom products.
Does a high transparency score mean I should buy the product?
No. Transparency measures information availability, not product quality, safety, or efficacy. A fully transparent brand could still sell a product that is ineffective or inappropriate for your specific situation. The score helps you know what you are deciding from — it does not make the decision for you.
Scoring criteria — what earns full marks per dimension
COA Visibility — 10/10 requires:
Batch-specific COA from an ANAB or ISO 17025 accredited third-party laboratory. Accessible via a direct link from the product page without login, account creation, or purchase. COA must show the batch or lot number corresponding to currently available inventory.
Lab Panel Clarity — 10/10 requires:
Full contaminant panel: potency by HPLC or equivalent; heavy metals by ICP-MS (minimum Pb, As, Cd, Hg); microbial counts including aerobic plate count, yeast and mold, E. coli, and Salmonella by USP methods; pesticide residues; residual solvents where applicable.
Ingredient Transparency — 10/10 requires:
Every ingredient named at species level (genus + species for mushrooms). Format stated (fruiting body, mycelium, extract, biomass). Extraction method stated where applicable. Standardization target stated (e.g., 30% beta-glucans). No proprietary blends where individual compound amounts cannot be determined.
Dosage Clarity — 10/10 requires:
Per-serving amounts stated in mg for each active ingredient. Serving size and daily frequency guidance stated. Total container quantity stated. Any protocol or schedule guidance (e.g., daily vs. as-needed) included. Where compounds are standardized, the per-serving standardized compound amount (not just the extract weight) is stated.
Support Availability — 10/10 requires:
Named company leadership verifiable via BBB, state business registration, or equivalent public record. Working phone number (not VoIP-only), direct email address, and real-time chat option. Physical address or registered business address stated. Response time SLA stated. About page present with company history.
Regulatory context
The legal framework the scoring dimensions operate within
Dietary supplements in the United States are governed by DSHEA (Dietary Supplement Health and Education Act, 1994). Unlike pharmaceutical drugs, dietary supplements do not require pre-market approval from the FDA to demonstrate safety or efficacy. The manufacturer is responsible for ensuring the supplement is safe before marketing, but the FDA does not evaluate or certify that responsibility in advance. This places the burden of verification on the consumer — which is exactly the gap the 100-point framework is designed to help fill.
Current Good Manufacturing Practice (cGMP) regulations under 21 CFR Part 111 require supplement manufacturers to have quality control procedures, but do not require batch-specific third-party testing or public disclosure of testing results. A manufacturer can be fully cGMP-compliant and never publish a single COA. The scoring framework awards points for going beyond the regulatory minimum — for making public what DSHEA does not require to be made public, precisely because that information is what a consumer actually needs.
The FTC has concurrent jurisdiction over advertising and marketing claims for dietary supplements under Section 5 of the Federal Trade Commission Act, which prohibits unfair or deceptive acts or practices. The FTC's standard is that advertising claims must be truthful, not misleading, and substantiated — meaning the advertiser must possess and rely on adequate substantiation before making claims. Joint FTC-FDA warning letters have been issued to supplement brands for unsubstantiated health claims, including several functional mushroom and adaptogen brands since 2023.
For Amanita muscaria specifically, the FDA has not formally defined muscimol as either a dietary ingredient or a new dietary ingredient (NDI) requiring pre-market notification. This regulatory ambiguity means the category occupies a grey zone — potentially permissible as a supplement without NDI status, but subject to challenge if adverse event reports accumulate. The 2024 Diamond Shruumz recall and the 2025 Blue Forest Farms warning letter both represent FDA exercising enforcement authority in this grey zone, using adulteration provisions rather than the NDI pathway.
Psilocybin-adjacent products face a different regulatory profile. Psilocybin itself remains Schedule I under the Controlled Substances Act, making products that contain or imply psilocybin federally illegal to sell as dietary supplements. Products in this category either contain functional mushrooms with no psilocybin content (legal but often marketed using psychedelic-adjacent language) or contain actual psilocybin (which falls outside the scope of this audit, which covers only legal US-market products). The scoring framework's Medical Claim Restraint and Legal Disclaimer dimensions are particularly critical in this category, where language choices carry significant regulatory risk.
How the scoring framework was calibrated
Why these ten dimensions and not others
The ten dimensions were selected by asking one question repeatedly: what information does a consumer need to make a decision about this product that they cannot reasonably verify without it? The answer changed somewhat depending on the product category, but converged on the same ten elements across functional supplements, Amanita/muscimol products, and psilocybin-adjacent nootropics.
Certificate of Analysis visibility was weighted first not because it is the most important dimension to any single consumer, but because it is the dimension that most directly determines whether all other claims can be independently verified. A brand that publishes a genuine batch-specific COA from an accredited laboratory has, by definition, answered at least part of the potency and contaminant question. A brand that does not has made those questions unanswerable without a laboratory of your own.
Medical Claim Restraint was given equal weight because it is a regulatory boundary, not a preference. DSHEA permits structure/function claims without pre-market FDA approval. Disease claims — statements that a supplement can diagnose, treat, cure, or prevent a specific illness — are not within that permission. A brand making impermissible disease claims is either unaware of federal dietary supplement law or has decided not to comply. Neither condition inspires confidence in the accuracy of other information on the same page.
Shipping Transparency and Refund Clarity were included because the 2026 audit repeatedly found documented consumer harm in these dimensions — subscription charges continuing after cancellation, non-consensual billing, return shipping costs not disclosed at purchase, and formal dispute resolution required to obtain refunds. These are not peripheral concerns. For a category where many consumers are purchasing online for the first time and cannot inspect the product before deciding, post-purchase protection is part of the total transparency picture.
Support Availability was calibrated on the assumption that a company willing to stand behind its product will make itself reachable before problems arise. Named leadership, verifiable contact information, and a response channel that does not require submitting a form and waiting are minimum signals of accountability, not premium features.
